需要对复杂数据排序 SQL Server 的帮助

这是我在 sql server 中的数据，我需要对其进行排序和显示

Table : MyTable
------------------
ID  Title
-----------
1   Geo Prism GEO 1995 GEO* - ABS #16213899
2   Excavator JCB - ECU P/N: 728/35700
3   Geo Prism GEO 1995 - ABS #16213899
4   JCB Excavator JCB- ECU P/N: 728/35700
5   Geo Prism GEO,GEO 1995 - ABS #16213899 GEO
6   Maruti gear box #ABS 4587

现在我想根据 GEO 和 JCB 等搜索词对数据进行排序

这些行将首先出现在 GEO 或 JCB 在这里找到最长时间 GEO 在 3 行中找到，JCB 在 2 行中找到。所以所有行都有 GEO 关键字，这些关键字将出现在顶部，下一个与 JCB 相关的行将会出现。不匹配的行终于来了。

再次将进行排序。在与 GEO 相关的行中……那些行将首先出现，其中具有最大的 GEO 关键字。相同的 JCB 相关行将被排序。

在这里，我给出的图像将显示我需要什么样的输出

在此处输入图像描述 我问了这个问题，得到的答案并没有完全满足我的要求。所以这是我为这个问题得到的sql。

CREATE FUNCTION [dbo].[Split] (@String varchar(8000), @Delimiter char(1))     
returns @temptable TABLE (items varchar(8000))       
as       
begin       
declare @idx int       
declare @slice varchar(8000)       

select @idx = 1       
    if len(@String)<1 or @String is null  return       

while @idx!= 0       
begin       
   set @idx = charindex(@Delimiter,@String)       
   if @idx!=0       
       set @slice = left(@String,@idx - 1)       
   else       
      set @slice = @String       

   if(len(@slice)>0)  
       insert into @temptable(Items) values(@slice)       

   set @String = right(@String,len(@String) - @idx)       
   if len(@String) = 0 break       
end   
return       
end

DECLARE @Sterm varchar(MAX) 
SET @Sterm ='GEO JCB'
;WITH SearchResult (rnum, title)
as 
(   
(select 1 as rnum,'Geo Prism GEO 1995 GEO* - ABS #16213899' as title)
union all
(select 2 as rnum,'Excavator JCB - ECU P/N: 728/35700' as title)
union all

union all
(select 5 as rnum,'Geo Prism GEO,GEO 1995 - ABS #16213899 GEO' as title)
union all
(select 6 as rnum,'dog' as title)
) 

select rnum, title from SearchResult
join 
( select lower(Items) as term 
  from dbo.Split(@Sterm , ' ')
) as search_terms

order by

declare @SearchItem varchar(1000)='GEO,JCB'

在 dbo.split(@SearchItem,', ') exec(' declare @tbl table(id int,title varchar(200)) ; with CTE as ( select 1 as id, ''Geo Prism GEO 1995 GEO* - ABS #16213899'' as Title union select 2 as id , ''Excavator JCB - ECU P/N: 728/35700'' as Title union select 3 as id, ''Geo Prism GEO 1995 - ABS #16213899'' as Title union select 4 as id, ''JCB Excavator JCB- ECU P/N: 728/35700'' as Title union select 5 as id, '' Geo Prism GEO,GEO 1995 - ABS #16213899 GEO'' as Title union select 6 as id, ''Maruti gear box #ABS 4587' ' 如题）

插入@tbl select id,Title from CTE

声明@tbl2 table(id int,T int,title varchar(200),Tl varchar(200),CC int) 插入@tbl2 (id,T,title,Tl) 选择 id,T,title,Tl from(select tb.id,sub.T,tb.title ,Tl from (select case '+@Instring +' else ''Other'' END as Tl ,count(*)T from @tbl group by case '+@Instring +' else ''Other'' END)Sub
join @tbl tb on tb.Title like ''%''+sub.Tl +''%'' )Sub1

声明 @Ttle varchar(max) 声明 @Tl varchar(max) 声明 @id int 声明 @i int=0 声明 @Nbr int=0 声明 Cursr Cursor for select title,id,Tl from @tbl2
open Cursr 从 Cursr 获取下一个到@Ttle,@id,@Tl while @@FETCH_STATUS =0 begin while (@i<=len(@Ttle)) begin if charindex(@Tl,@Ttle)!=0 set @Nbr =@Nbr +1 set @ ttle =stuff(@Ttle,charindex(@Tl,@Ttle),len(@Tl),'''') set @i=@i+1 end

     update @tbl2 set cc=@Nbr where id=@id 
     set @Nbr =0

从 Cursr 获取 next 到 @Ttle,@id,@Tl end

select id,T,title,Tl,CC from
(select id,T,title,Tl,CC from @tbl2
union select id,0 as T,title,'''' as Tl,0 as CC from @tbl where id不在 (select id from @tbl2 ))S1 order by T desc,CC desc ' )
